Why can't Canon MX328 printer fax?

First, put away the document paper to be faxed.

Then dial the number on the fax machine.

Finally, press the "black and white" start key,

At this time, the fax machine began to dial to send a fax to the other party, but it did not explain that this operation was only suitable for the other party to automatically receive the fax, nor did it explain how to operate if it was necessary to reply the fax manually.

Here I tell you how to reply the fax manually.

First, connect a phone to another phone interface of the all-in-one machine.

Then, put the file to be transmitted into the fax sending port,

Finally, dial the other party's fax number on the newly received phone to answer manually, and press the "black and white" start button after the other party gives the fax signal.

One thing to note is that this all-in-one machine does not have its own microphone, so if the other party answers the fax manually, it needs to add an extra phone, so that it can automatically receive the fax manually like other fax machines.
